Empty results after upgrading


I’ve been using the YaCy version 1.924 running Robinson mode, and just downloaded 1.926 from https://release.yacy.net/. I copied the DATA folder from the older install to the new one. Any search returned 0 results (screenshot below).

Index browser showing there are 4,730 documents which is correct, and http://localhost:8090/ViewFile.html?viewMode=sentences&url=https%3A%2F%2Fwww.xxxxxxxx&show=Show+Metadata&search=x appears to have correct documents. I tried to restore from a previous dump, but the search results are still empty.

Both installs are unzipped from compiled tarballs, on MacOS Mojave (10.14.6).

Many thanks in advance for help on this.
